Cephalopods
A body can only be divided into 2 identical halves by a plane that passes through the center of the body on a longitudinal axis.
Bilateral
A group of organs that perform the animals broadest function.
Organ system
These cells allow organisms to respond to their environment.

All chordates have three characteristics
a notochord, a nerve cord, and a throat pouch
What is a tissue
A hard outer covering is called the
exoskeleton
An ectotherm produces a little or a lot of internal heat
Sessile and Motile
The nerve chord connects these things
brain to nerves
This is made up of different tissues and performs more complex functions.
Organ
